RAILWAY ROLLING-STOCK.

SPECIFICATION forming part of Letters Patent No. 635,799, dated October31, 1899.

Application tiled March 9, 1898. Serial No. 673,166. (No model.)

To all whom t may concern:

Be it known that I, DANIEL MCOOOL, a citi zen of the United States,residing at the city of St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Railway Rolling-Stock, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompany# ing drawings, formingpart of this speciication, in which- Figure l is a cross-sectional viewthrough a car embodying my invention. Fig. 2 is a detail View of aportion of a roof, showing the manner of applying my invention thereto.Fig. 3 is an enlarged sectional view through a portion of a roof securedin position on a car, and Fig. 4 is a detail view of the cementitioussubstance used in my improved car construction.

This invention relates to a new and useful improvement in railwayrolling-stock, and particularly to the construction of what are known asbox-cars,7 the object being to arrange a cementitious substance thereinto prevent the entrance of rain, dust, cinders, rbc., into the carthrough the sheathing-boards of the roof and also to provide awaterproof trough or flooring for the car when it is used .as arefrigerator-car.

W'ith these objects in view the invention consists in the arrangement,construction, and combination of the several parts, all as willhereinafter be described and afterward pointed out in the claims.

In the drawings I have shown in Fig. l a cross-sectional view of what isknown as a refrigerator-car, while in Figs. 2 and 3 I have shown anordinary box'car.

In the drawings, A indicates the side wall of a car, which, as shown inFig. l, is provided with paper or felt or other non-heatconductingmaterial and in some constructions dead or live air spaces. The sidewall of the car, however, has little to do with my invention, as itconsists, so far as the ilooring of the car is concerned, in thearrangement of a cementitious substance B between the upper floor properand the subfloor. These floors are preferably inclined to conduct thedrippings to a central trough, whence the water is led to the exteriorthrough a pipe O. In applying this substance in building the car I laythe subiioor D in position and then arrange the cementitious substance Bthereon. This substance, as shown, extends upwardly any desired distanceagainst the inside wall A. By the provision of this cementitioussubstance B in the flooring and up the side walls of the car the sillsand lower iiooring are protected from moisture, and consequentlypreserved. Such a iioor is of great value also in cattle-cars, where themoisture will penetrate into the lnortised joints of the sills and rotthe same.

The cementitious substance above referred to preferably consists ofburlap treated with a lnagnesian cement, said burlap being laid inposition while in a plastic state and the top flooringplaced in positionthereon while the burlap is still wet, the burlap, with its cement,acting as a binder between the upper and lower floors. The magnesiancement, forming the composition with which the burlapis treated, is madeby combining magnesium oxid and magnesium chlorid, the two making a bathin which the burlap is immersed, said burlap forming a fibrous fillerfor the cement.

The roof is also provided with a cementitions filler and binder, (markedE in the drawings.) The subroof or inner sheathing F is preferablyarranged longitudinally the car, of tongue-and-grooved material, whichis nailed to the carlines, the upper roof-sheathing G being arrangedtransversely the car. The burlap, treated as above described, is laidacross the lower sheathing F and down along the side walls of the car,as at e, after which the upper sheathing G is placed in position and thecrown-mold or faciaH arranged to protect the depending edges e. Theupper sheathing G preferably extends some distance beyond the crown-moldII to conduct off the water.

As shown in Fig. 4, the cementitious substance B consists of two-plyburlap treated as above described; but it is obvious that one or moreplies could be .used with equal success.

I-Iaving thus described my invention, what IOO I claim, and desire tosecure by Letters Patent, is-

l. In a car the combination of an inner sheathing of boards, an outersheathing of boards, a wall at an angle to said sheathings andcomprising an innerand an outer sheathing, and a continuous layer ofcementitious material between and uniting said inner and outer boardsheathings and extending between the sheathings of said wall,substantially as set forth.

2. In a car, the combination with a board suboor, a board iioor proper,and a side wall comprising an inner and outer sheathing, of a continuouslayer of cementitious material between said suboor and floor proper andextending up between .said inner and outer side wall-sheathin gs,substantially as set forth.

In a car, the combination with a floor comprising an inner and outersheathing, and a side wall comprising an inner and outer sheathing, of acontinuous layer of cementitious material between said inner and outerioor-slieatliings and extending up between said inner and outer sidewall-sheathings,substantiall y as described.

4. In a car, the combination of a floor comprising an inner and outerboard layer, side Walls comprising an inner and outer sheathing, acontinuous layer of cementitious material between and uniting the floorlayers and extending up between and secured to the inner wall-sheathing,and a root comprising an inner sheathing, an outer sheathing and acontinuous cementitious layer between and uniting said layers andext-ending down the outer face of the side walls, substantially asdescribed.

5. In a car, the combination with a floor proper and its subfloor, of acementitious material arranged therebetween, of side walls A and A',said cementitious material continuing up the side walls, acentrally-arranged trough, and a drip-pipe C extending from said trough,substantially as described.

6. In a car, the combination with the inner and outer sheathing-boards,of a cementitious substance arranged between said sheathingboards, saidcementitious substance being applied in position while in a moist orplastic state and penetrating the pores of the wood to make the samewaterproof, after which said cementitious material hardens, continuingsome distance down the side and end walls of the car, substantially asdescribed.

7. In a car, the combination with the inner and outersheathing-boards,of a cementitious material arranged between said sheathingboards,saidcementitious material continuing some distance down the side and endwalls of the car, and a crown-mold for protecting the cementitiousmaterial at the sides and ends of the car, substantially as described.

S. In a car, the combination with the nclined floor proper and itssubfloor, of side walls A and A', said walls A' resting upon the fioorproper,a cementitious material arranged between said iloor proper andits subfloor, the ends of said cementitious substance continuingupwardly and being secured to said walls A', a roof formed with an innersheathing F and an outer sheathing G, a cementitions material arrangedbetween said sheathings and continuing over, or extending down along,the face of the walls A, and a crownmold II arranged outside of saidcementitious material to hold the same in place, substantially asdescribed.

In testimony whereof I hereunto a'Iix my signature, in the presence oftwo witnesses, this lst da;7 of March, 1898.

DANIEL MCCOOL.
